The SSND-MLTIDML 8-12 is an 8.5" sound with a continuously shifting diameter rather than a fixed shaft — tight entry segments, a long tracking zone, and a final barrel peak, built for extended wear.

Details

  • Overall length: 8.5"
  • Insertable depth: ~8" (200 mm)
  • Entry tip: 7.0 mm
  • Entry segments: 8.5 mm → 9.0 mm → 9.5 mm, closely spaced
  • Main tracking shaft: 11.0 mm easing to 10.0 mm, 3.5" long
  • Peak barrel: 11.7 mm (35.1 Fr)
  • Retention valley: 9.5 mm
  • Base: Expanded safety flange

How it works

The 7mm tip steps up quickly through three closely spaced segments (8.5mm, 9mm, 9.5mm), then rises to 10mm before settling into a smooth 11mm-to-10mm tracking section that runs 3.5" — long enough for the muscle to relax rather than stay under continuous pressure. Near the base, the shaft rises once more to an 11.7mm peak before narrowing sharply into a 9.5mm retention valley, where the muscle seats against the expanded flange.

Choosing your silicone firmness

Bob recommends #10 (Medium) — it keeps the multi-stage profile well-defined and comfortable for longer wear sessions.

Color options

#18 and #30 are available in pure translucent silicone.
#00-20, #00-50, and #10 use a translucent white base and can be mixed with our standard colors.

Please note

This is an intermediate piece, well suited to moving up toward 11–12mm diameters gradually rather than all at once.
Use appropriate lubrication and never force insertion. Stop immediately if you experience pain, bleeding, or significant discomfort. Inspect the sound before each use and do not use it if damaged.
